Storage buildings

You can create an indoor porch by simply installing the front wall in the second or third roof truss. You could do the same with the rear wall of course.

Do the storage buildings have gutters and drainpipes?

By default, the storage buildings are supplied without gutters and drainpipes. You can optionally order the matching drainage system. The Kroftman drainage system for storage buildings is entirely made of galvanised sheet steel. The system consists of drain pipes on both sides of the storage building with upright pipes (plus final bend) down to the ground. The capacity of the gutter and the number of upright pipes is tailored to the size of the storage building. The standard available colours are pearl-light grey (RAL9022) and anthracite grey (RAL 7016). You can find more details on the download page.

Can I make a storage building with an entry gate?

You can make a covered entry gate by installing the front wall in the second or third truss. You of course have the same option at the back.

What is Dripstop®?

Dripstop® is a felt layer attached to the roof sheets of the H-series storage buildings. It ensures that valuable goods and materials remain dry, even in case of condensation.

Can I place a window in a storage building?

Kroftman only supplies storage buildings without windows. If you nevertheless would like to place one or more windows in your storage building, you must do this yourself. In that case, keep in mind that the warranty on the construction and cladding will then lapse.

Can the man door also be placed on the left?

For the H-series, the man door can effortlessly be placed to the left or the right of the roll-up door. And rotating clockwise or counter clockwise.

For the E-series, the man door can only be placed to the right of the roll-up door.

Do the storage buildings comply with the NEN 1087 ventilation standard?

The storage rooms ventilate at the back and the front under the roof trim (flashing), but this hasn’t been calculated. Ventilation standards are not necessary for storage buildings unless the application prescribes these (for instance storing chemicals).

Is it possible to install solar panels on the roof of the storage building?

Yes. To calculate the maximum snow load, you have to subtract the weight of the solar panels from the snow load.

Example: if the snow load for the storage building in question is 1,2kN/m², then the roof can withstand 120 kilos of snow per square meter.

If the solar panels for example weigh 40kg, 80kg remain. In a region where the snow load is less than 0,8kN/m² (80kg per square meter), the storage building can be equipped with solar panels.

All man doors are equipped with a cylinder lock. The roll-up doors have a latch for a padlock (not included). The storage buildings can therefore be entirely sealed off.

Can I paint the storage building?

You can, but the warranty will then lapse. The sheet material has a polyester top coating. If this is covered by an extra layer of paint, the coating no longer offers full protection.

Can I place a higher or wider roll-up door in the storage building?

It is possible to install a different roll-up door. We then supply the entire storage building without a roll-up door so you can order a roll-up door with the desired dimensions yourself.

For a higher roll-up door you must construct the storage building on a raised foundation to increase the opening for the roll-up door.

Are the storage buildings available in different colours?

Yes. You can choose from different colours for the various components (except the doors) of the H-series storage buildings. No extra costs are charged for this. Check the product page or download the colour card for an overview of the colour options.

Can two storage buildings be permanently constructed beside each other?

No, the laws and regulations prescribe that there must be at least 100 cm between them. A distance of a meter is also necessary for installation.

Can the storage building (partly) be constructed without sheet material?

You can do this by adding extra wind bracing. The structural calculations are then however no longer applicable. Contact Kroftman to discuss what is necessary and possible in your situation.

Can the roll-up door be moved to the side wall?

Yes. You will then receive extra sheet material to seal the opening at the front.

Do you offer insulation?

Our standard buildings are uninsulated. If you wish to reduce extreme temperatures or condensation you can insulate your building yourself cheaply and easily. This is done by installing common insulating panels (such as sandwich panels, Polystyrene, EPS, PIR, Styrodur®, Isover® or Fastfixx®) tightly between the truss tubes. The seams should be sealed with insulation tape or caulking. (see image) Ideally the insulation panel thickness should equal the depth of the tubes; 75mm or 50mm. (see construction drawings) Due to the remaining thermal bridges and uninsulated roll-up door/skylights these buildings are less suitable for full heating. Please be aware that the maximum snow load allowance should be reduced with the weight of the roof insulation.

Do you have structural calculations available?

Of all our storage buildings, storage tents and container shelters we have structural calculations available in German. These are available on request and free of charge.

For these structural calculations we work with German engineers. These structural calculations always meet the ′Eurocode′ standard supplemented by German codes DIN+DIBt ensuring wide European and International acceptance. To maintain the legal status, we only provide the original untranslated documents in the German language. Should this cause you any difficulties, you can use these documents as a basis to ask a local engineer to draw up a structural calculation in your own language which meets your local requirements.

Can the man door be placed on the left as well?

The man door can be installed to the left or right of the roll-up door with very little effort. You can also choose between left or right-hand opening.

How are these storage buildings anchored?

Kroftman storage buildings can always be placed without a foundation. This distinctive advantage allows you to achieve huge savings on the overall project costs. This allows one to place a storage building much more quickly and inexpensively. The storage building can also be placed on Stelcon® sheets, asphalt, pavement and even on compacted earth, gravel or rubble.

Have a look at our special page about the anchoring options.

What about rainwater drainage?

We advise you to order the matching drainage system with your steel building. The Kroftman drainage system for steel buildings is entirely made of galvanized (Aluminum Zinc) sheet steel and is therefore a solid and durable solution with 20 years warranty. The system consists of roof gutters on both sides of the steel building with standpipes (plus final bend) to the ground level. The capacity of the gutter and the number of standpipes is tailored to the size of the steel building. The colors Aluminum Zinc (uncoated) and Anthracite (RAL7015) are in stock. More details can be found in the download section.

I need a different length. Is that possible?

We provide standard building lengths. However, during installation you can easily adjust the length to the desired size by cutting all horizontal parts between the last two trusses.

Is it possible to install a steel building on pavement or asphalt?

For temporary or semi-permanent installation it is usually allowed to use earth anchors. For this purpose Ø25x1100mm earth anchors can be ordered. It is important to have an even installation surface. Any unevenness must be equalled out. Prepare 30mm holes with a drill hammer.

Is it easy to install a roll-up door?

A roll-up door is easily installed with 3 people within 30 minutes. Watch the instruction video.
